Answer 2

To simplify the given expression:

(A² - 3a) / (A² - 25) ÷ (A² - 9) / (A² + 5a)

You can use the following steps:

1. Factor the denominators:

(A² - 3a) / ((A + 5)(A - 5)) ÷ (A² - 9) / ((A + 3)(A - 3))

2. Rewrite the division as multiplication by the reciprocal of the second fraction:

(A² - 3a) / ((A + 5)(A - 5)) * ((A + 3)(A - 3)) / (A² - 9)

3. Now, you can cancel out common factors in the numerators and denominators:

[(A - 3)(A + 3)] / [(A + 5)(A - 5)] * [(A + 3)(A - 3)] / [(A + 3)(A - 3)]

4. Multiply the fractions:

[(A - 3)(A + 3)(A + 3)(A - 3)] / [(A + 5)(A - 5)(A + 3)(A - 3)]

5. Cancel out the common factors in the numerator and denominator:

(1) / [(A + 5)(A - 5)]

So, the simplified expression is:

1 / (A² - 25)

You can further factor the denominator if needed:

1 / ((A + 5)(A - 5))
